Prince Philip Parties With Cameron Diaz, Gwyneth Paltrow, Who Advises: 'Don't Tell The Queen!'

There are the usual conspirators in late-night party crime – Lindsay Lohan and Calum Best, Justin Timberlake and Mila Kunis, Pippa Middleton and her high-class squeeze. A more surprising trio emerged in London last night, 90-year-old Prince Philip, seasoned Californian Cameron Diaz and doyenne of healthy living Gwyneth Paltrow, who even advised: “Don’t tell the Queen!”

The indomitable Duke has never let his royal status get in the way of having a good night out, particularly when there’s some high-class beauty to admire – seems like he’s not letting his noctagenarian status interfere either.

According to the Telegraph, the gang of three had started the evening at a drinks reception at the recently refurbished Arts Club in Mayfair where the Duke stayed to listen to Paltrow perform an impromptu concert, following a plaque-unveiling ceremony earlier in the evening.
